      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

2007 Merc 115 4 Stroke efi Limp Mode

Recommended Posts

Hey guys, wondering if anyone might be able to point me in the right direction.  I have the motor as stated in the subject line.  As of late it's been going into limp mode after driving it for a little while.  Thought it was an over heating issue at first because the alarm and limp mode would only happen after running it for a period of time.  Like this morning, a buddy and I were driving across the lake, maybe a 10 minute trip, and the alarm came on and went in limp mode all the way back to the launch.  It has been stuttering during acceleration.  Not sure what was going on there.

After we ran it this morning checking out the motor putts with stuff, we put it back in the lake.  Ran alright at higher speeds, but still stuttered during acceleration and while at 3500rpm would have a stutter occasionally too.  Then after running it for a while it went back down to limp mode running pretty rough and only at slow speeds.

The impeller is streaming water just fine even at idle.  The water coming out is only luke warm.  The engine block even after running for a while is probably considered very warm to the touch but not hot.  I can put my hand on it and leave it there.  I have changed the thermostat as initially I thought it was an over heating issue.  

I've just changed the spark plugs, flushed the injectors and tested the coils, and all them seem alright.  Didn't notice anything alarming.  Put the muffs on in the driveway and it wouldn't go above 2k rpm and ran pretty rough at rpms above idle.  Idle seemed somewhat alright. 

In the two seasons I've owned it I've winterized it with Marine Stabil, and have only used ethanol free/non oxygenated gas.  The voltage also seems alright as when it's running the graph is showing it's producing 14.1 volts, or down to 13.9 depending how many accessories I have on.  

I really would rather not take it in.  I was quoted $115 for the first hour of diagnostics.  

Anyone have any thoughts??

Thanks!
Marc

The alarm is a code and will indicate the problem . Is it a series of beeps or a solid beep ? The alarm went of on mine this spring similar to yours . It was a steady beep that  indicated over heating . Had me stumped because the motor was pumping a water stream and the alarm would stop and start intermittently . Turned out to be that the water pump that I had gotten replaced a year or so ago (by a cheap back yard mechanic ) had not been properly installed and that seals where missing and replaced with silicone . The mechanic that repaired the motor the second time explained that because the pump was incorrectly installed, air was getting sucked in the lower unit resulting in poor cooling even tho the motor had a stream it wasn't properly cooling . I did also find that once the motor went to limp mode it would stay there until I went into neutral, even though the  issue was temporary  the computer would not clear its self

Yesterday in the driveway it was one long beep.  Other times I believe it's been either 3 or 4 beeps.  I'll try it again today.  Are we able to plug these motors into a code reader like cars to get error codes?  The mechanic said that's not possible but given these motors can record hours at tom intervals would think they would have error codes. 

Yours was even streaming water like it should?

The oil and filter were changed when i got it out of storage this year.  The oil level is in the normal range too.

Symptoms fit the "coolant sensor failure"    Runs bad since computer thinks motor is cold and makes stuff too rich.  Then figures out sensor is screwed up and goes to limp mode.   

You could replace the sensor and see. 

Could also be a thermostat stuck open, although I'm not sure whether that would cause limp mode. 

It looks like sensor is maybe 50 bucks.

    • agreed i use an app called geo gone that scrubs all data. I have locations turned off but also scrub every photo just encase.
    •   I am not a big Football guy but feel sorry for those folks as well.  IMO if you are just wanting to watch some good hockey with no desire to Win the cup then you are just a casual Fan and that is all good....but I see it differently....it all starts with Hope. As far as the crazy talk this is a quote directly from Liepold out of the Pioneer Press at the start of this season “Anything short of winning the Stanley Cup would be a disappointment,” Leipold said. So my guess is he's getting impatient too, he wants to bring a Cup to MN, he sees we have not been improving, and IMO he's setting the table to give Fletch his walking papers if in fact we don't make a deep run this year.
    • Starting with the 2018 model year (released in March 2017), all 8' wide Yetti's have a 72" x 80" rear ramp door. Many common interior finishes reduce the width down to 70". There are 17'+V front and 21'+V front tandem hydraulic models available. In addition, these Traxx Editions (toy haulers) have adequate hauling capacity for your UTV plus gear.    Good luck on your search!    https://yettioutdoors.com/products/#traxx 
    •   This ^^^^^^^^^^^^^   I think the difference is that when message boards like this one were more popular, the info was archived in a user friendly format. Anyone could find the info about Lake Waconia because it was cataloged and searchable under a heading or search terms that made sense. Now the info being offered in groups on Facebook is just a bunch of bits here and there and if you don't catch it when it is first posted, the chances are you will never see it.  
    •   yes this is a good point. But also remember to not be like a particular poster that used to frequent the forums who alleged to catch the same exact fish on different casts. But the exif data showed that the 2 pics were taken within a second of each other and the b.s flag was thrown.
    • Been on facebook? there's plenty of chatter on there.
    • Any suggestions?   I'm running out of ideas. My wife is working today but I am home in the snowstorm all day. We just had chicken wild rice soup last night and chili not too long ago so no soups and I don't feel like standing outside by the grill or smoker in this weather so what should I make for supper?
    • From Strikemaster.....   This size blade has been discontinued since 1981. Wow.......so my auger is at best only 37 years old.......If it could only tell stories.
